TISSUE - MUSCLE

Muscle tissue

contracts or shortens with a force

and therefore is responsible for

movement

Skeletal Muscle

attaches to bone and is responsible

for body movement

● long and cylindrically shaped with

many peripherally located nuclei

Cardiac Muscle

● cylindrical branching cells with a

single central nucleus

● found in the heart andis responsible

for pumping blood through the

circulatory system

Smooth Muscle

● forms the walls of hollow organs,

the iris of the eye and other

structures

● its cells are spindle shaped with a

single central nucelus

Striated

- refers to the striped appearance of

the muscle fibers due to organized

protein filaments

Intercalated disks

- are specialized structures found

only in cardiac muscle (heart

muscle). They are dark-staining

lines that appear at the junctions

between individual cardiac muscle

cells.

Skeletal Muscle

● Structure: Long, cylindrical,

striated cells with many nuclei at

the edges

● Function: Moves the body

(voluntary control)

● Location: Attached to bones or

connective tissue
